Oxford English Dictionary outs gay Princeton

What... is going on? The world's been shaken, and I don't know quite where to begin.The Oxford English Dictionary, one of the world's renowned comprehensive English dictionaries, has an entry for "Princeton."And it's really, really, really surprising and erotic and graphic and scarring like walking in on your parents and forever changes "Princeton" in a mind and where did it come from?What am I on about? This:

Princeton, n.Designating a form of male homosexual activity in which the penis is rubbed against the thighs or stomach of a partner.

Yeah. I don't... No, I don't know what to say. And even more outrageous, the etymologies:

1965 S. FRIEDMAN Totempole 265, I should have known..it would be the Princeton rub or nothing. 1969 W. H. AUDEN in N.Y. Rev. Bks. 27 Mar. 3/4 My guess is that at the back of his mind, lay a daydream of an innocent Eden where children play ‘Doctor’, so that the acts he really preferred were the most ‘brotherly’, Plain-Sewing and Princeton-First-Year. 1972 B. RODGERS Queens' Vernacular 154 Princeton style,..fucking the thighs. 1980 Times Lit. Suppl. 21 Mar. 324/5 ‘Princeton-First-Year’ is a more condescending version of the term ‘Princeton Rub’; that is, coitus contra ventrem. 2004 D. BERGMAN Violet Hour iii. 105 He arrives there still a virgin, without even the benefit of the ‘Princeton rub’.

Wait, what's that, Patrick Bateman from American Psycho?Well. Maybe that Princeton-Yale rivalry is just some weird gay love "thing" that can only be expressed with petty bickering and Yale sucks!...But sucks what?(shoutout to Emily Rutherford '12 for the great find)
